Question

diffine accelaration and write its si unit

Answer 1

Answer :

$\bigstar\:\underline{\boxed{\bf{\purple{Acceleration:}}}}$

⇒ Acceleration is defined as the rate of change of velocity. In other words, It is a ratio of change of velocity to the time interval.

⇒ It is a vector quantity having both magnitude as well as direction.

⇒ It can be positive, negative or zero.

⇒ Dimension formula : [L¹Tˉ²]

⇒ SI unit : m/s²

Formula : a = (v - u) / t

• a denotes acceleration
• v denotes final velocity
• u denotes initial velocity
• t denotes time

Answer 2

The rate of change of velocity is called Acceleration

It is denoted by " a "

$\boxed{ \sf{Acceleration \: (a) = \frac{v - u}{t} }}$

Where ,

u = initial velocity

v = final velocity

t = time

The SI unit of acceleration is " m/s² "

The dimensional formula of acceleration is $\sf{ {M}^{0} L {T}^{ - 2} }$

It is " vector quantity "

It can be positive , negative or zero
